Description

[Detailed Description of the Invention] The present invention relates to a card feeding device for a magnetic card recording/reproducing machine.

In general, a magnetic card recording/reproducing machine moves a magnetic head back and forth along the magnetic surface of a magnetic card, and simultaneously positions the magnetic card in a direction perpendicular to the direction of movement of the magnetic head in conjunction with the reciprocating movement of the magnetic head. The present invention provides a new card feeding device for such a magnetic card recording/reproducing machine, in which a magnetic card is held and both widthwise sides of the card are supported by guides. A card stand configured to slide along the guide by the action of a tension spring, a rack provided at a widthwise end of the card stand, a saw gear provided integrally with a pinion meshing with the rack; a tilting plate having a rear stopper that engages with the saw teeth of a saw gear, the rear stopper engaging and disengaging from the saw teeth by tilting;
When the rear stopper is disengaged, it engages with the saw teeth at a position shifted in the rotational direction of the saw gear by half the pitch of the saw teeth, and when the rack moves against the tension spring, the saw teeth engage A front stopper is attached to the tilting plate so as to be pushed down.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a card stand for firmly holding and sending a magnetic card 2. The card stand 1 is equipped with a card slot 3 on the front side, and a magnetic card can be inserted into the card slot 3 through the card slot 3. A stopper 4 that protrudes from the recessed state when the magnetic card 2 is inserted and prevents the magnetic card 2 from being removed.
Moreover, its upper surface 5 is made of a transparent material so that insertion of the magnetic card 2 can be confirmed.

Furthermore, the card stand 1 is supported at both ends in the width direction (left and right sides) by guides 6.6, and can freely slide back and forth along the guides 6.6, and is always supported by a tension spring 7 in the rearward direction. It is designed so that it can be pulled and moved backwards.

In addition, a rack 8 is provided on the side surface in the width direction of the card stand 1, and a pinion 9 that meshes with the rack 8 is provided.
A saw gear 10 provided integrally with the pinion 9 is rotatably supported by a fixed member (not shown).

As shown in FIGS. 3 and 4, a rear stopper 12 provided on the upper surface of the steel gear 10 by tilting about a fulcrum 11 is attached to the sawtooth 10' of the steel gear 10.
A tilting plate 13 is provided which engages with the steel gear to stop the 100 rotations of the steel gear, and the tilting plate 13 is tilted by being pressed by a push rod 15 against the force of a tension spring 14. and the rear stopper 12 stops the steel gear from rotating 100 times,
Furthermore, when the force of the push rod 15 is removed, the inclined plate 13 returns to its original position due to the force of the tension spring 14, and the steel gear 10 is disengaged from the rear stopper 120, causing the steel gear 10 to move in the direction of the arrow. It is designed to allow free rotation.

Further, a rotating plate 18 is attached to the tilting plate 13 via a pin 16 and can be freely rotated in a parallel state with an appropriate distance between the tilting plate 13 and the washer 17. , and the rotating plate 18 can be rotated downward against the force of the tension spring 19, but upward rotation is prevented by a locking portion 20 provided on the tilting plate 13. It looks like this.

Further, the rotary plate 18 has a front portion positioned so as to be forward in the rotational direction of the steel gear 10 by h of the pitch P of the saw teeth 10′ of the steel gear 10 with respect to the rear stopper 12 provided on the tilt plate 13. A stopper 21 is integrally formed.

Next, the feeding operation of the magnetic card will be explained.

In FIG. 1, first, the card stand 1 holding the magnetic card 2 is pulled downward (toward the front) against the tension of the tension spring 7 and moved.

At this time, the steel gear 10 is rotated by the rack 8 and pinio/9 in the direction opposite to the arrow.

Although the front stopper 21 is engaged with the steel gear 10,
Since the front stopper 21 can be easily rotated downward, the steel gear 10 can easily rotate in the direction opposite to the arrow while pushing down the front stopper 21 with the saw teeth 10'. can.

When an attempt is made to stop the card holder 1 from being pulled back, the sawtooth 10' of the steel gear 10 is locked by the front stopper 21, causing the steel gear 10 to move in the direction of the arrow. Since it is no longer possible to rotate in any direction, it remains stopped.

When the push rod 15 is pushed in the direction of the arrow from this state, the engagement between the stopper 21 and the sawtooth 10' is released.

Then, the card stand 1 moves in the direction of the arrow due to the tension exerted by the tension spring 7, and rotates the steel gear 10 in the direction of the arrow via the rack 8 and pinion 9.

After the steel gear 10 has rotated four times, the pitch P of the saw teeth 10', the saw teeth 10 are stopped by the rear stopper 12.

At this time, the next (front) serration 10' to be locked has already reached the front stopper 21 and the position P, so if the push rod 15 is returned to its original position in this state, the rear stopper 122, 1 is released, the front sawtooth 10 moves 1/2P, and is locked to the front stopper 21.

Therefore, the operation of pushing and pulling the push rod 15 (・
The steel gear 10 can be rotated by /, P, and the card stand 1 and the magnetic card 2 can be intermittently and continuously fed in a predetermined amount in the direction of the arrow via the pinion 9 and the rack 8. .

Furthermore, in a device equipped with the above-mentioned feeding device, if the magnetic head is brought into contact with the lower magnetic surface of the magnetic card 2 and moved from side to side, recording on the magnetic surface applied to the entire surface of the magnetic card 2, The magnetic card 2 can be played back, and in conjunction with the left and right movement of the magnetic head.
It is also possible to send it effectively.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

According to the above-mentioned card feeding device of the magnetic card recording/reproducing machine of the present invention, if the card stand is first pulled and moved against the tension of the tension spring, then the card can be read by simply tilting the tilting plate using the push rod. The magnetic card can be fed intermittently and continuously without requiring constant driving force, and since the magnetic card is fed through a gear mechanism, the operation can be performed reliably. If the push rod is operated in conjunction with the movement of the magnetic head that moves left and right along the magnetic card, recording or playback can be performed continuously on the entire magnetic surface of the magnetic card, and The device has advantages such as being simple in configuration and less likely to break down.
